steve-lunarg 26d3145334 HLSL default function parameters
This PR adds support for default function parameters in the following cases:

1. Simple constants, such as void fn(int x, float myparam = 3)
2. Expressions that can be const folded, such a ... myparam = sin(some_const)
3. Initializer lists that can be const folded, such as ... float2 myparam = {1,2}

New tests are added: hlsl.params.default.frag and hlsl.params.default.err.frag
(for testing error situations, such as ambiguity or non-const-foldable).

In order to avoid sampler method ambiguity, the hlsl better() lambda now
considers sampler matches.  Previously, all sampler types looked identical
since only the basic type of EbtSampler was considered.

Glslang Tests based on the Google Test Framework

This directory contains Google Test based test fixture and test cases for glslang.

Apart from typical unit tests, necessary utility methods are added into the GlslangTests fixture to provide the ability to do file-based integration tests. Various *.FromFile.cpp files lists names of files containing input shader code in the Test/ directory. Utility methods will load the input shader source, compile them, and compare with the corresponding expected output in the Test/baseResults/ directory.

How to run the tests

Please make sure you have a copy of Google Test checked out under the External directory before building. After building, just run the ctest command or the gtests/glslangtests binary in your build directory.

The gtests/glslangtests binary also provides an --update-mode command line option, which, if supplied, will overwrite the golden files under the Test/baseResults/ directory with real output from that invocation. This serves as an easy way to update golden files.
